0

Schritte zur Lösung

x \to 1 + lim (ln (x) ln (x - 1))

Umformung für L'Hopital

= x \to 1 + lim (\frac{ln ( - 1 + x )}{\frac{1}{l n ( x )}})

Wende das L'Hopital Theorem an

= x \to 1 + lim (\frac{\frac{1}{- 1 + x}}{- \frac{1}{x l n ^{2} ( x )}})

Vereinfache

\frac{\frac{1}{- 1 + x}}{- \frac{1}{x l n ^{2} ( x )}} : - \frac{x ln ^{2} ( x )}{- 1 + x}

= x \to 1 + lim (- \frac{x ln ^{2} ( x )}{- 1 + x})

Wende das L'Hopital Theorem an

= x \to 1 + lim (\frac{- ln ^{2} ( x ) - 2 ln ( x )}{1})

Setze den Wert

x = 1

ein

= \frac{- ln ^{2} ( 1 ) - 2 ln ( 1 )}{1}

Vereinfache

\frac{- ln ^{2} ( 1 ) - 2 ln ( 1 )}{1} : 0

= 0

x \to \infty lim (x (e^{\frac{1}{x} - 1}))

x \to 1 lim (sin (x - 1))

x \to 4 lim (3 x + 2)

x \to 0 lim ((x)^{(x^{2})})

x \to \infty lim ((1 - \frac{2}{x})^{\frac{x}{2}})
